P; l. LANGLYKKE 'VALVE RAISING DEVICE Filed Feb. 6. y 1925 members 45 and 6 are substantial duplicates vof each other, one being the ectype of the as to bring the heads 8 and 9 and their notches in register, as shown in Fig. 4, and the ear 13 ofeach member 'lies between the ears 12 and 13 of the associate member, as shown in F ig. 1. -The ears 1Q and 13 of each member by this arrangement may be the same distance apart.

The members 5 and 6 are transversely curved throughout to lend strength and lo improve their appearance.

The eective operating part of the latch bar 15 is Wholly within the curved portion of the handles and the spring' 20 lies within the concave portion of one 'f said handles or members.

The inner confronting' edges of the members 5 and 6 between the pivotal point and the end of the heads 8 and 9 are substantially parallel on two straight lines. This produces a structure 'of mi Ximum strength and a continuous wedge shape outline from end to end when the members are in the positions shown in Fig. 2.

Having'described. my invention what l 'claim as new and desire to secure by Letters Patent, is

1. A tool of the character described comg prising two substantially duplicato members, transversely curved in cross section providing confronting concave surfaces,

and hinged together; al widened notched head on like ,vends of each Imember providing a pair of rigid prongs, Ione on each side of its notch; a notched latclnbar pivoted to one member and extending thru a per- 'oration in the other member, the wall of said perforation cooperatingl.,with said lnotches to hold the; jaws separated a predetermined distance. and a spring extending from the member in which said latch baris pivoted to said bar and partly con- :terasse tained in the concave portion of said mem ber to actuate said latch bar.

2. A tool of the character described comprising two substantially duplicate members, ol uniform thickness, each member having a pair oi hinge ears containing registering perforations, like ears ot said members being laterally oil-set to cause register of the respective heads; a pin passing thru the tour ears to hinge the members to- ,f fethcr. said members each having a head containing a notch and said notches brought into alignment by the off-set hinge ears.

8. .l tool of the character described comprising tivo substantially duplicate members each of uniform thickness and trans? versely curved throughout, each member having a pair of hinge ears containingr registering perforatioi'is, a like ear of each pair oll ears being laterally displaced and the ears ol the members being equally spaced, with one ear ot' one member between the pair oi ears of the other member to bring the members into transverse alignment; a pin passing through said -four ears to hinge the members together and a latch to hold the members separated.

4. A tool of the character described comprising tn'o substantially duplicate Incinbers each of uniform thickness and transversely curved to produce a transversely arched formation from the head thereof to its further end; a widened notched head on one end of each member, cach member providingr a pair ot lixed rigid prongs, one on cach side of its notch and the edges of the prongs bounding the notches located at an angle from the outlines of the member to form a spring seat; a pair of hinge cars extending inwardly from each member, one ear of each pair located between flic pair of the other member; a pin extending tln'u said four ears to hinge the members together and a spring pressed latch to hold thc heads separated.

In testimony whereof I hereunto subscribe my name.
